-12(5/6a-7/8)+1/14(3 1/2a-1 2/5)
Answers
First change mixed fractions to be full fractions
-12(5/6 a -7/8) + 1/14 (7/2 a - 7/5)
Now multiply out
-12(5)/6 a -12(-7)/8) + 7/14(2) a -7/14(5)
-60/6 a + 84/8 + 7/28 a -7/70
-10a + 10.5 + 1/4a - 1/10
-10a + 0.25a +10.5 -0.1
-9.75a + 10.4
*if this =0 and you need to solve for a then
9.75a=10.4
a= 10.4/9.75
a=16/15

SOLVE FOR X!!
(will mark brainliest))
Answers
Answer:
x=15
Step-by-step explanation:
Hello there!
The shown angles are vertical angles
if you didn't know vertical angles are congruent
That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15
Solve for x. Each figure is a trapezoid.

You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?
Answers
Answer:
$0.33 per cookie
Step-by-step explanation:
The unit rate (cost per cookie) is
$4
---------------- = $0.33 per cookie
12 cookies
Answer:
Roughly $0.34
Step-by-step explanation:
Set up an equation:
Variable x = cost of one cookie
12cookies/$4 = 1cookie/x
12/4 = 1/x
Cross multiply
12 × x = 4 × 1
12x = 4
Divide both sides by 12
12x ÷ 12 = 4 ÷ 12
1x = 4/12
x = 0.333333
x = is about $0.34

Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²

The perimeter of a rectangle is 20 feet. The width is 4 feet less than the length. Find the dimensions of the rectangle. Then find its area.
Answers
Answer:
length = 7 ft
width = 3 ft
area = 21 sq ft
Step-by-step explanation:
let l = length
let l - 4 = width
2l + 2(l - 4) = 20
2l + 2l - 8 = 20
4l = 28
l = 7
w = 3
Area: 7 x 3 = 21
